Cute little game! You nailed the theme. I think maybe to expand this idea you could have a pattern of three sounds. Maybe you hear a tv, a dog and a robot and you have to select them in that order. Congrats on submitting a game for the jam!

Very faithful to the theme, would be nice if after making my selection the timer went to 0 because sometimes I know instantly and I find myself waiting doing nothing

Well the game is short but it was fun nonetheless. I got the weird question mark sound for like 3 times in a row at the start and I had not idea what was going on, but then I understood. It's a simple mechanic but it can be really fun. Adding some variance to sounds, or adding and removing objects so they are not always the same could definitely spice things up.
